MACHINE FOR SHAVING AND CUTTING STEREOTYPE AND OTHER PLATES.

SPECIFICATION forming part of Letters Patent No. 224,755, dated February 17, 1880.

. Application filed December 9, 1879. I

To all whom it may concern Be it known that I, WILLIAM A. WRIGHT, of (Jentreton, in the State of New Jersey, have invented a new and useful Improvement in Apparatus for Shaving and Cutting Stereotype and other Plates, Printers Leads, and other Furniture, &c., which improvement is fully set forth in the following specification and accompanying drawings, in which Figure 1 is a top or plan view of the apparatus embodying my invention. Fig. 2 is a central longitudinal vertical section thereof in linem m, Fig. 1. Fig. 3 is an end View, partly sectional.

Similar letters of reference indicate correspondin g parts in the several figures.

Myinven'tion consists in a carriage mounted on a suitable table and supporting an adjustable blade, whereby, when plates, slugs, leads,

&c., are placed on the table the blade may be moved thercover, and thus shave or cut their. faces true and uniform, and to any desired extent.

It also consists in suspending the blade on flexible arms, whereby there is no outward strain on the blade.

It also consists in connecting the bladesupporting arms independently of each other to adjustable collars, so that either side of the blade may be adjusted with the greatest nicety.

Referring to the drawings, A represents a flat-top table, supported on suit-able feet or legs; and B represents acarriage, which is fit- 3 5 ted to said table so as to have a longitudinal sliding motion'thereon, said motion being imparted in the present case by rack-bars a,

connected to the carriage and meshing with pinions 1), whose shaft b is mounted on the 40 table A, and provided with a suitable power or crank wheel, as at c. i

From the forward end of the carriage B rises a head, 0; to which isconnected, by means of screw-bolts d, an upright cutter or blade, D,

l said bolts cl passing through slots 0 into the head, whereby the blade is vertically adjustable, so as to shave or cut a greater or less extent. Attached to the blade at opposite sides a are arms E, whose upper ends are pivoted to collars F, which areconnected to a shaft, Gr,

mounted on lugs or bosses H, which rise from the head 0. To the shaftGis also connected an arm or lever, J which is conveniently accessible from the front end of the apparatus, and provided with an index, f, which sweeps over a graduated are, 9, on the face of one of the lugs H. p

The collars F are adjustably connected to the shaft G by means of set-screws h, and thus are independent of each other, and the arm or lever J may be fixed to said shaft G in any suitable manner.

The arms E are flexible and preferably formed of spring metal.

The operation is as follows: The plate, lead, 6 or other piece or article to be shaved or out on its face is placed on the bed or tableAagainst the abutment A, and the knife D properly adjusted by raising or lowering the leverJ until the index f sets at the graduation g, which corresponds with the depth of shaving or cutting to be accomplished. The bolts or screws d are then tightened, so that the knife retains its adjusted position. The carriage is then advanced by operation of the power or crank wheel a, and the knife acts on the surface of the piece or article beneath it, thus shaving or cutting it as desired or required. The carriage is then run back, and the piece or article turned and reapplied to the tableA, so that another side thereof is presented or a fresh piece or article is applied, and the car riage again advanced until the work is completed.

Owing to the flexible arms E, which are con nected to the knife or blade D, there is no rearward or forward strain on the top of the latter, and thus the knife is not liable to be shifted from its adjusted position.

As the collars F are movable" on the shaft 0 G independent of each other, either side of the blade D may be raised and lowered, whereby the adjustment of the knife may be accomplished with the greatest nicety and accuracy.

The shavings and cuttings may fall from the 5 table and drop into a box or other receptacle suit-ably applied.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- 10o 1. The carriage B, with the blade D susarms, in combination with the adjusting-colpended from the adjusting-shaft G, substanlars F, independent of each other, substan- 15 tially as and for the purpose set forth. tially as and for the purpose set forth.
